This seems to commit to ST and IO really being the same. Does stToIO already make this commitment? I can't tell, but if not, I oppose making that commitment in the "public" interface.

There's a function stToIO that is defined in GHC.IO and exported from Control.Monad.ST. There's another function, ioToST, that's also defined in IO, but it isn't exported from Control.Monad.ST. I propose that it be exported from Control.Monad.ST.
